Looking forward to a high performance JVM on the ARM server. Is there a way to rent an ARM server which has a high-performance JVM ?

Oracle JDK has full support for C2 and hard float on ARM 64. That code is not in OpenJDK. Red Hat is working on C1 in OpenJDK for Java 9.

  Full support for C1 & C2 is available in OpenJDK 7,8 & 9. Prebuilt binaries may be downloaded from http://openjdk.linaro.org/releases.htm http://openjdk.linaro.org/releases.htm. Sources are upstreamed for jdk9 (http://hg.openjdk.java.net/jdk9/dev http://hg.openjdk.java.net/jdk9/dev). For jdk8 they are maintained in the OpenJDK aarch64 project (http://hg.openjdk.java.net/aarch64-port/jdk8 http://hg.openjdk.java.net/aarch64-port/jdk8). For jdk7 they are maintained in the IcedTea project (http://icedtea.classpath.org/hg/icedtea7-forest http://icedtea.classpath.org/hg/icedtea7-forest). The default java on Ubuntu trusty (14.04) and vivid (15.04) LTS releases is openjdk.

  There was a talk about the port last year, with slides: https://archive.fosdem.org/2014/schedule/event/openjdk_aarch64_update/ https://archive.fosdem.org/2014/schedule/event/openjdk_aarch...
